To all whom it may concern:

7 Be it known that I, LEROY L. SALFISBERG, a citizen of the UnitedStates, and a resident of Newark, in the county of Essex and State ofNew Jersey, haveinvented an improvement in Attaching Devices, of whichthe following is a specification.

The present invention relates to an improvement in attaching devices,such for example as may conveniently be utilized in connection with thesecuring of snap fasteners and the like to flaps, curtains or otherarticles. One of the objects of the invention is to provide attachingmeans which may readily be formed as an integral partof the fastener orother device and which will render it possible to secure suchfastenor orother device to a flap or the like-by a simple manual operation, itbeing contemplated that the device can afterward be removed andtheposition changed if desired without destroying any .of the parts..One embodiment of nay-invention is il lustrated'in the drawingsaccompanying the present specification, and in which,

Figure 1 is a top plan view of the male portion of a snapfastener devicesecured to a flap ,or other article.

Referring to the drawings, the attaching device forming the subjectmatter of my invention may conveniently be embodied in either or bothmembers of a snap fastener such as that illustrated in Figure 9. Themale member of such device, shown more fastener device.

Specification of Letters Patent. Ppf gnted Apr. 18 1922 Applicationfiled October 20, 1921. Serial No. 509,008. i

particularly in Figures 4 and "5 consists of a base portion 1, aprojecting button 2 and splrally disposed attaching prongs 3 and 4 whichare preferably integral with the base 1, cut from the material thereofand displaced with their freeends deflected so as to he in attachingposition substantially as shown in Figure 5. The prongs have curvededges which taper to a point at their free ends. In operation, to attachthe male portion of the snap fastener to a flap or cover, the pointedends of the prongs 3, and 4 will be inserted in the material, and upontwisting the device in the direction of the arrow, said prongs 3 and 4will pierce the cloth or other material. the prongs, 3 and 4 to therebynot only protect them but also to make a moresecure attachment, saidprongs are adaptedtocooperate with a shield 5 provided with spacedoffset portions 6 and 7 forming retaining members for receiving saidprongs 3 and 1.

is shown in Figure 9,.the prongs in this position are effectivelycovered on the one side by the material of the flap orcover and onthe/other side by the shield 5.

The same type of attaching device is applicable to the female portion ofthe snap Asindicated in Figures 7 and 9," the female portion of the snapfastener includes a base member 8, an inwardly turned peripheral flange9 by 1111634118 of which a spring retainer 10 is held in position toengage and retain the button 2 of the male portion. Said retainer isprovided with a central opening 11 having slots 12 extending radiallytherefrom to form a plurality of spring retaining members 13. Where thebottom wall of the base 8 is solid or imperforate, the spring members 13may be bent as shown in Figure 9 to make room for the button 2 betweenthe retainer 10 and the bottom of the base member 8. The base 8 is alsoprovided with an at taching device consisting of spirally arrangedprongs 14 and 15 which, in operation, are deflected so that their endswill piece the material to which the female memher is to be attached.The shield 5 may or may not be used as desired.

As shown in Figure 7, the prongs 1 1 and 15 are punched out of metalsurrounding an opening in the base 8 instead of at the outer edge of abase member as in Figures 1 and 5. This produces a construction which iseasily manufactured and which is securely In order to cover attachableto fabric materials and the like by a simple twisting movement.

The mode of aflixing the attaching device to any given material may bevaried, for example, so that'the point'of the prongs, instead of beingpositioned adjaeentto the end surface of the material, will bepositioned on the same side as the base 1. This is effected by partiallysecuring the device in position and then turning the free ends of theprongs upwardly to pierce the material a second time thus bringing theprongs back on the sameside as the base 1; Where this mode of attachmentis contemplated, it is desirable to allow some space between the upperend of the prong and the base 1. Thus, as shown in Figure 10, a portionof the material of the base will be cut out to form slots 16 and 17 toaccommodate the material.

It is contemplated that the attaching device hereinabove described inconnection with a snap fastener may be adapted to a variety of uses suchas buttons, paper clips and the like, in addition to the one disclosedabove in connection with the snap fastener. In this particular instance,however, the utility or the device will be apparent and includes variousfeatures such as the simplicity of the construction, the ease with whichthe device is applied to a supporting object such as a flap or cover,the secure fixing of the device in position when once applied and itsadaptability to" various kinds of types of material such for example ascloth, leather and the like.

I claim as my invention i 1; An attaching device comprising a base andmaterial piercing prongs extending from one slde thereof and at an anglethereto, said prongs having curved longitudinal one side thereof and atan angle thereto, saidprongs having curved longitudinal edges taperingfrom the base to a terminal point,

and forinln'g prong retaining loops.

3. A1 attaching device comprlsing a base and material piercing prongsextending from one side thereof and at an angle thereto, said prongshaving curved longitudinal edges tapering from the base to a terminalpoint, the inner edge of each prong being spaced from an adjacentportion of the outer edge of the base to permit a thickness of thematerial to which the device is attached to be interposed between saidprong and the base when the prong is in operative position andsubstantially flush with the base.

at. A snap fastener comprising a male portion and a female portion, saidfemale portion comprising a base having an inwardly turned peripheralflange,-a resilient male engaging portion, and attaching means integralwith said base and comprising prongs extending from one side" thereofand at 'an angle thereto, said prongs having curved longitudinal edgestapering to a terminal point. r

5. A snapfastener comprising a male portion and a female portion, saidmale portion comprising a base, a projecting button, and attaching meansintegral. with said base and comprising prongs extending from one sidethereof and at an angle thereto, said prongs 6. An attaching devicecomprising abasehaving an opening and prongs disposed,

along the edge of said opening and extending fromone side of the baseandat an angle thereto, said prongs having curvedlongi tudinal edgestapering from the base to a terminal point. i

' In testimony whereof, Ihave'signedmy name to this specification this18th day of October, 1921. V
